Application filed. February 19, 1918. Serial No. 218,099.

To all whom t may concern: v

Be it known that ll, HENRY H. KLINGBIEL a citizen of the United States, residing at El Reno, in the county of Canadian and State of Oklahoma, have invented a new and useful Wrench, of which the following is a specification.

'lhe device forming the subject matter of this application is a wrench adapted to be used in inaccessible places, such as about the engine of an automobile, for loosening bolts and nuts, and one object of the invention is to provide a structure of the kind'hereinafter described, which will be well adapted for use above set forth.-

Another object of the invention is t0 provide novel means for mounting the sprocket' wheels whereby motionis transmitted to the part which rotates the nut.

Another object of the invention is to provide a device of the class mentioned which will be strong and comprise few parts subject to deterioration or damage. i

llt is within the province of the disclosure to improve generally and to` enhance the utilityqof devices of that type to which the present invention appertains.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in th'e combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precisel embodiment of the invention herein disclosed can be made withinthe scope of what is claimed, without departing from the spirit of the invention.

ln the accompanying drawings s l Figure 1 shows in elevation, a dev1ce con structed 1n accordance with the invention;

Fig. 2 is a longitudinal section taken approximately on the line 2-2 of Fig. '1;

Fig'. is a section taken approximately on the line 3-3 of Fig. 1;

Fig. 4 isl a section taken approximately on the line 4-4 of Fig. 1; and

Fig. 5 is an elevation showing one of the shafts.

'llhe device forming the subject matter of this application includes a body, made up of opposed side plates 1 and 2, held together and spaced apart by means of securing devices 3, connecting the side plates 1 and '2 intermediate their ends. A laterally extended` tubular sleeve 9 is threaded at 10 into the side plate 1 or is otherwise connected therewith. The numeral 4 marks a tubular' shaft having cylindrical ends 5. One of the ends 5 is journaled in the inner end of the sleeve .9v and the other of the ends is journaled in the side plate 2, the shaft 4 embodying a polygonal hub 6 located between the side plates 1 and 2. rlhe tubu' lar shaft 4 has a .polygonal bore 7. A sprocket Wheel 8 is mounted on the polygonal hub 6 and is held thereon against independent rotation, the sprocket-wheel being located between the side plates 1 and 2, as clearly disclosed in Fig. 4. rlhe numeral 11 marks an operating member j ournaled in the sleeve 9 and substantially filling thesame, so far ascross section is concerned, the sleeve cooperating with the operating member to afford increased strength. The 'operating member 11 embodies a laterally eX- tended crank or loop 12, carrying a rotatable thrust head 14, the operating member, generally stated, resembling a bit stock. rl`he operating member 11 terminates in a ref duced, polygonal end 15, received against rotation in the polygonal bore 7 of the shaft 4. rl`he part 15 of the operating member l1 extends outwardly beyond the side plate 2 and carries a Washer 16 and a cotter pin 17, these elements coacting with Athe side plate y2 to prevent the operatingmember 11 from thevshaft is received between the side plates 1 and 2,- as shown inFig. 4.

'llhe invention comprises a shaft, denoted generally by the numeral 18, andv embodying a reduced cylindrical end 19 journaled in the sideplate 1, as shown in Fig. 3. The shaft 18 includes, further, a polygonal hub 20, located betweenthe side plates 1 and 2, and a bearing portion 21 journaled in the side plate 2. Projecting laterally from the bearing portion 21 of the shaft 18 is a head 22, shaped to receive a nut or other object which is to be rotated. The head 22 is of larger diameter than the bearing portion 21 of the shaft 18, and there is formed, therefore, a shoulder 23, which, ycoacting with the outer face of the side plate 2, prevents the shaft 18 from moving in one direction. The shaft is prevented from moving in an opposite direction, longitudinally, by means of a washer 24 and a cotter pin 25 carried by the end 19 of the shaft, these elements coacting with the outer face of the side plate 1. A sprocket wheel 26 is held on the polygonal hub 20 of the shaft 18 and is disposed between the side plates 1 and- 2.

The sprocketwheels 8 andv26 are united by a chain 27.

In practical operation, when the member 11 is rotated by means of the crank 12, the tubular shaft 4 land consequently the sprocket wheel 8 will be rotated, motion being transmitted to the sprocket wheel 26 by way of the sprocket chain 27, the sprocket wheel 26 rotating the shaft 18 and rotation being imparted to the head 22 which, being engaged with the nut or other object, will serve to loosen or tighten the same.

The device forming the subject matter of this application is simple inl construction and embodies few parts, the construction being such that the article can be built readily and be taken down for repair, should occasion demand.

with nut engaging means; a sprocket wheel carried by the second shaft; and a sprocket chain connecting the sprocket wheels.

2. In a device of the class described, a body comprising side plates; a shaft including bearing portions journaled in the side plates, a hub between the bearing portions, and a head on one bearing portion, the head embodying nut engaging means and defining a shoulder coacting with the outer face of one plate; securing means carried by the other bearing portion and coacting with the outer face of the other plate; a sprocket wheel carried by the hub; a'second shaft mounted for rotation in the body; a sprocket wheel carried by the second shaft; a chain connecting the sprocket wheels; and a laterally extended operating member interengaged with the second shaft.

In a device of the class described, a body made up of side plates; a laterally projecting sleeve carried by one side plate; an operating member mounted to rotate in lthe sleeve and comprising an angularly explates; a sprocket wheel mounted on the shaft between the plates; and a chain connecting the sprocket wheels.

In testimony that I claim the foregoing as my own, I have hereto aiixed my signa- .ture in the presence of twov witnesses.
